Hi I am studying C++ programming and I am trying to make a Vector Addition Calculator. I get it to work for only 2 quadrants but the rest don't seem to work. Here is the code that I have written. It might be hard to follow but I would appreciate any help thats.
#include<iostream>
#include<vector>
#include<string>
#include<stdio.h>
#include<math.h>
//#define PI 3.14159265
using namespace std;
int main()
{
int magvec1;
int angvec1;
int magvec2;
int angvec2;
double vector1x, vector2y, vector3x, vector4y, Rx, Ry ,R3, R4, R5, angtheta;
float ang;
float angl;
float mag;
float angle;
float Rangle;
float TempAngle1,TempAngle2;
float radang1, radang2;
const float rad = 0.017453293;
const float pi=3.14;
cout<< "Hello! Welcome to Ramiro's Vector Addition Calculator." <<endl;
cout<< "Please input Magnitude: ";
cin >> magvec1;
cout<< "Please input Angle: ";
cin >> angvec1;
cout<< "Chose second Magnitude: ";
cin >> magvec2;
cout<< "Please second Angle: ";
cin >> angvec2;
float ANGCOS1,ANGSIN1,ANGCOS2,ANGSIN2;
radang1 = angvec1 * rad;
radang2 = angvec2 * rad;
TempAngle1=radang1;
TempAngle2=radang2;
cout<<"the rad angle1 is " <<TempAngle1<<endl;
cout<<"The rad angle2 is " <<TempAngle2<<endl;
ANGCOS1=cos(radang1);
ANGSIN1=sin(radang1);
ANGCOS2=cos(radang2);
ANGSIN2=sin(radang2);
cout<<"The cos1 is "<<ANGCOS1<<endl;
cout<<"The sin1 is "<<ANGSIN1<<endl;
cout<<"The cos2 is "<<ANGCOS2<<endl;
cout<<"The sin2 is "<<ANGSIN2<<endl;
//radang2 = angvec2 * rad;
vector1x = ANGCOS1*magvec1;
cout<<" x componet of vector 1 is "<<vector1x<<endl;
vector2y = ANGSIN1*magvec1;
cout<<"y component of vector 1 is "<<vector2y<<endl;
vector3x = ANGCOS2*magvec2;
cout<<"x component of vector 2 is "<<vector3x<<endl;
vector4y = ANGSIN2*magvec2;
cout<<"y component of vector 2 is "<<vector4y<<endl;
Rx = vector1x + vector3x;
cout<<"Resultant Vector x "<<Rx<<endl;
Ry = vector2y + vector4y;
cout<<"Resultant Vector y "<<Ry<<endl;
R3 = Rx*Rx;
R4 = Ry*Ry;
R5 = R3 + R4;
angtheta= (Ry/Rx);
cout<<"AngTheta is "<<angtheta<<endl;
angl= atan(angtheta);
cout<<"The Arc angle is "<<angl<<endl;
angle= (angl*180)/ pi;
cout<<"The Angle is "<<angle<<endl;
Rangle= angle+180;
cout<<"Angle= "<<Rangle<<endl;
if (Rangle > 90 && Rangle <180)
Rangle = Rangle + 180;
else (
else (angvec1>90 && angvec2<180);
Rangle = Rangle - 180;
mag = sqrt(R5);
/*if (Rx>0&& Ry>0)
angl = atan(angtheta);
if (Rx<0&&Ry<0)
*/ angl=(atan(angtheta)* pi);
cout<<"The Resultant Angle is "<<Rangle<<endl;
cout<<"The Resultant Magnitude is "<<mag<<endl;
system("pause");
return(0);
